Build a Galera cluster on a Docker Swarm cluster made of Docker Machine-provisioned VMs

This repository contains scripts to create a Docker Swarm cluster of VirtualBox VMs and then start a Galera cluster of Docker containers running on the Swarm cluster.

The script create-cluster.sh will go through the following steps:

  • Create the VMs, one to host the consul container which will act as the keystore for the Docker Swarm cluster, then some more as members of the cluster.
  • Create an overlay network spanning all the Swarm cluster nodes so containers on one node can directly connect to others on other hosts.
  • Create an initial Galera container which will act as an initial master for the Galera cluster.
  • Create additional Galera containers and connect them to the growing Galera cluster.
You can’t perform that action at this time.
